If the S&P adopt those rules would there be any index fund that is S&P without the new rules?
Vanguard doesn’t use S&P, because they wanted low fees and the license was expensive. They use CRSP’s index rules.
I checked and it looks like new stocks get added to the CRSP index at the next rebalancing, which is September. So, even the knockoff S&P adds it quickly.
BTW, CRSP was run by University of Chicago, but got sold recently to Morningstar, a mutual fund company.
An index fund like the S&P500 is not the S&P500. It is stuck competing in a world of low margin pain.
I sincerely hope S&P and Nasdaq rollback the SpaceX-targeted changes, but unfortunately I seriously doubt it.
Dimensional funds have a type of index factor funds that roughly track these indices without strict adherence to S&Ps inclusion rules. That's the only one I'm aware of.
IZZ, or in other words fuck em.
